Awesome pure CSS tooltips at your fingertips

Install

Using Bower

bower install -S hint

Using npm

npm install -S hint

Usage

Just give your elements a nice tooltip in HTML. When hovered, the hint will appear.

<span data-hint='foobar'>Foo Bar</span>

You'll get a nice little tooltip. Remember to include the CSS in your styles!

By default, the :after pseudo-selector is used. This means you can use the :before pseudo-selector for your own purposes. If you want the data-hint to use :before, then you must use the hint-before class on the element as well.

<span data-hint='foobar' class='hint-before'>Foo Bar</span>

You can also use the aria-label attribute.

<span aria-label='foobar'>Foo Bar</span>

If you want the aria-label hint to use :before, then you must use the hint-before class on the element as well.

<span aria-label='foobar' class='hint-before'>Foo Bar</span>

Hints have a z-index of 5000.

JavaScript

The CSS will only get us so far, and we must add a tiny bit of JavaScript if we want a little functionality. This is not critical to hint, and is therefore considered an optional feature. The JavaScript code enables the following features.

• Hints are docked to the visible viewport so that they aren't cut off when they're near the edge
• If hints are even wider than the viewport itself, then they are rendered in multi-line, setting the max width to the viewport width
• You can define a maximum width to avoid hard-to-read long hints in wide viewports
• When the JavaScript snippet is used, hints transition into view a second after the target element is hovered

To include the JavaScript, just use the following snippet if you're using CommonJS, or refer to the dist directory for the compiled distributions.

require('hint');

To set the maximum hint width, do:

require('hint').maximumWidth = 650;

You can also set it to 'auto', which means the full viewport size will be used if the tooltip exceeds the viewport size in length. In practice, 'auto' means Infinity will be used. The default maximumWidth value is 650 pixels wide.
